WASHER Filed' sept. 9, 1927 Patented oct. 7, 1930 p PETER EsfHAuGEmoE Dawson v PATENT i OFFICE" CREEK, BRITISI-ICOLUMBIA, CANADA i WASHER` application inea` september 9,1927, seriaifivo. 213,565," and in` canada 'siepteiiuuer 2o; 1926.

The invention relates ,to improvements `in washers andan object of theinvention isto provide `a washer which can be opened to perinitit tobe placed on a shaft, bolt or such alike from' theside'aiid subsequently locked thereon, thisallowinglone to readily take up any looseplay without havingto disniount any of the eXisting parts.

A further'object is to construct the washer l0 so that itvcan be adjusted to fit Vthe shaft or the like and such that it can be manufactured in au simple, durable and inexpensivenianiier. `A further object is to construct thewasher so that the engaged j thereofcanibe posi- 15 tively held against lateralshifting and fun ther such that the thickness of the washer' can be readily varied'toaccommodate the space which it is required to fill by utilizing the washer.

2W ,TW ith the above more important objects Y in view, the invention consists essentially in f ing, in which Fig. 1 is a perspective view of the hinged washer sections, the filler plates being removed.

Fig. 6 is a perspectiveview of the type of `washer shown in Figure 5 and showing thc modified arrangement of filler plate. A

In the drawing like characters Yof reference indicate corresponding parts in the several figures. Y

The main part of the Washer according to Figures 1 to 4 inclusive, comprisestwo halves or sections 1 and 2, the section 1 being `what might be termed a male section and 2 a female section. The sections are of an arcuate shape and in Figure 1 are hingedly connected to- Vby forcibly expanding thejaw Sto` release saineas the fullthickness of either of the sections. v

-The male member of the section 1 isl provided'with an extendingjaw 4`havingfthe Vouter edge thereof formedfwith a series of ratchet teeth 5- which are arrangedinore or less concentric tothe center pointV of the washer. The body ofthe washer isnotched away underlying thejaw as indicated at 6L The female member `ofthe washersections`2` has the free end thereof provided with a lengthwise extending slot which is'adapted Y to` receive tlieljaw 4 and which provides an Y outer spring aw 8` having a series of ratchet teeth 9 onfthefinner'side thereofadapted to engage; withteeth 5I l e e l vWhen 'tliejaws are pressedltogether, Vthe teethof the jaw'S are adapted to springpast theteeth ofthe jaw 5, the arrangement of the teethbeingsuch that when engaged theyre- Vsist the pulling apart oflthe jaws. The linw ger formed at 1() on thefemale section vacts* Vwith the remaining part of the washer to `center the washer'on the shaft, rod or the like on" which it is placed Thewasher can `beopeiied the teethorby! springing thermale aw latere e ally toescape the teeth of the other aw."

The'washer` as shown in Figure 1 is what might be termed a thin washer which canxbe used where acomparatively small amount of S play is to be taken upf` VIt will be observed l that the sections ofthe saidwasher are provided with pairs of holes 11 and .12, 13 and 14, thegpurpose of'which will be 'shortly eX- plained`. i

`Therey there is `considerable play to be taken up, a comparatively thick washer will berequired and accordingly it is desirable to provide filler plates and a washer `equipped with filler platesis, shownin Figures 3 and 4. In thistype, the sections of thejwasher Vare made in thesame manner as shown in Figures 1 and Qywith theexception that the Vattached or hinged ends thereofiarejnot formediiithesame way.- The pairs of filler,`

plates and 16 utilized are attached to the washer 'sections by rivets 17 passing through holes 18 formed in the washer sections, these holes corresponding to the holes 11 and 12, 13 and 14 provided in the sections of the Washer appearing in Figure 1. It will be observed that the-lower ends ofthe filler plates 15 extend beyond thelower end of' the washer section 1 to provide side lugs and that the lower end of the section 2 of the washer enters between thesevside lugs,` and is pivotally attached thereto by a rivet 19.,

` Obviously one could supply several pairs of filler plates to. increase the thickness of the' washer and' at` such time, would utilize longer rivetstov hold the parts together. Thelfiller plates shown in Figure 3`can be used .on the washerv shownY in Figure 1 by passing the rivets through the holes 11, '12, 13 and lit. It will be particularly observed that when the filler plates have been closed together as shown in Figure 4 and held by the rivets, they prevent any possibility of lateral shifting of the jaw 4 which at such time is engaged with the jaw 8.

In Figure 5 I have shown a further modiicaton of the washer and wherein the male and female sections are not hingedly connected together` but are entirely separate. The male member in this instance instead of being supplied with one'j aw has the ends thereof terminating in two jaws'21 and 22 whichv are provided on the outer side. with ratchet teeth 23 and 24and the femaler member 25 has the ends terminating' in spring jaws 26 andl '27 fitted at their inneredges with ratchet teeth 28 and 29 which are adapted'to engage 23and 24eA when the washerv sections are forced together.V This-form of washer is taken apart inthel same manner as the former'and is held on the shaft by forcibly pressing the teeth of the jaws into engagement. Y KVf `In Figure 6, I have showna modified type of ller plate utilized with the type of washer shown in`Figure 5. .The-stiller plate 3() 1s originally inthe form Vof a cylinder having the ends thereof longitudinally -slit to provide a plurality of tongues 31. -v `When the liller .is in use, the tongues thereof are bent outwardly against the. face of therwasher sections in the manner shown in`Figure 6.

By providing my Washer and filler plates, itis very easy to take up loose play where such occurs. If there is not muchloose play, the washer without the filler plates is used. Where there is considerable loose play, one selects illerplates which will accommodate the amount of play and attaches themY to the washer sections by the rivets and then passes the washer onto the shaft and locks it. Vhat I claim'as my invention is Y LA washer comprising arcuate male and female members Vhingedly connected together, itheV male @member having the free end thereof terminating in a jaw provided at its outer edge with a series of ratchet teeth and the female member having its free end terminating in a spring jaw provided on the inner edge with a series of ratchet teeth complementary to and engageable with the former ratchet teeth and within the latter spring jaw with a guide finger underlying the jaw of the male member and adapted to close the open centre of the washer in all adjusted positions ofthe jaws. e

2. A washerl comprising arcuate male land female sections hingedly connected together, the male section having the free end thereof termin'ating'in a jaw provided at its outer edge with aseries of ratchet teeth and the female section having'its free end terminating in a spring aw provided on they inner edge with a series of ratchet teeth complementary to and .engageable with the former ratchet teeth and within the latter this 23rd day of August, 1927.
